Abstract

Land degradationis amajor factor indecreasing the productivity of the land. Themostfrequently land degradation
occurred is due to surface runoff and erosion. One of the causes of the surface runoff and erosion is human
treatment.Human treatment of the land can accelerate or reduce surface runoff and erosion. This study aims to
determine the effect of both tillage systems and herbicide on surface runoff and erosion on crop cassava field in
laboratoriumlapang terpaduAgriculture Faculty,University ofLampung.The experimentwas designas a factorial
in randomized complete block design with four block. This experiment used multislot devicermethod with size 4
x 4meter. Treatment consists of two factorswhich are tillage systemand herbicide. The results of this experiment
indicate that tillage system did not affect surface runoff and erosion significantly and herbicide treatment
increase surface runoff compare to treatment without herbicide, which is 32,8 mm and 24,6 mm, but did not
significantly affect erosion.
